农药是农业生产中常见的生产资料,又是对环境有害的有毒化学品,如何处理好这对矛盾,是保证农业持续发展和保护生态环境的重大课题。农药的生态效应是研究环境中的残留农药对各种环境生物影响的剂量关系,及其对生态系统的影响。保护的重点是一些有益的昆虫与有经济价值的生物,如天敌、鸟类、鱼类、蜜蜂、家蚕、蚯蚓和土壤微生物等。以及国家重点保护的濒危珍稀生物。
Pesticide is a common production material in agricultural production, but also a toxic chemical harmful to the environment. How to deal with these contradictions is an important issue for ensuring the sustainable development of agriculture and protecting the ecological environment. The ecological effect of pesticides is to study the dose-effect of residual pesticides in the environment on various environmental organisms and their impact on ecosystems. Protection is focused on beneficial insects and economically valuable organisms such as natural enemies, birds, fish, bees, silkworms, earthworms and soil microbes. As well as the rare and endangered species under the state’s key protection.
